Arbitrage calculator

Enter the best price at each book. If the combined implied probability is under 100%, there's an arb — and this shows how to split the stake.

The profit shown is what survives rounding to whole cents — not the textbook figure, which assumes you can stake fractions of a penny. Real arbs also assume both bets are accepted at these prices and neither is voided.

Worth knowing: sportsbooks limit or close accounts that arb consistently. That is a practical reality of the strategy, not a legal one, and it is not something a calculator can price in for you.
